  • Safety study of intravenous infusion with self-made perfluorocarbon emulsion in rats

    Objective To assess the safety of intravenous infusion with self-made perfluorocarbon emulsion (PFE) in rats.Methods 35 Wistar rats were randomly divided into a normal control group and six PFE groups (n=5 in each group).The control group was intravenous injected with normal saline and six PFE groups with PFE.Blood samples were obtained from the PFE groups 5 min after injection via vena orbitalis for perfluorocarbon (PFC) measurement.The control group were sacrificed at 2 hours after injection,and the six PFE groups were respectively killed at 2 h,4 h,6 h,24 h,48 h and 10 d after injection.The blood levels of PFC,PaO2,GPT,GOT,BUN and Cr were measured.Pathological changes of lung,liver and kidney were also observed.Results All rats were in good health state after PFE intravenous injection with no obvious pathological changes in liver and kidney.PFC was wide distributed throughout the pulmonary alveoli and capillaries.The levels of GPT and GOT were higher in the PFC groups at 2,4,6 and 24 h than which in the control group (all Plt;0.05),but there were no significant difference between the PFE 10 d group and the control group.The levels of BUN and Cr had no remarkably differences in all groups.Blood PFC concentrations were (20±1.8)mg/mL,(1.8±0.7)mg/mL,(1.5±0.6)mg/mL,(1.2±0.4)mg/mL,(0.5±0.2)mg/mL,(0.2±0.03)mg/mL,0 mg/mL in the PFE groups respectively at 5 min,2 h,4 h,6 h,24 h,48 h,10 d after injection.PaO2 of the PFE 2 h group was significant higher than which in the control group [(119.2±8.6)mm Hg vs (99.6±4.7)mm Hg,Plt;0.05].Conclusion Intravenous injection with PFE (10 mL/kg) can enhance PaO2 with good safety and no obvious influence on pathology of lung,liver and kidney,so may be used for the treatment study of acute lung injury.

  • Vitrectomy and autologous platelet concentrate for the treatment of idiopathic macular holes

    Purpose To assess the efficacy of pars plana vitrectomy,autologous platelet concentrate and gas tamponade for the treatment of full-thickness idiopathic macular holes. Methods The procedures consisted of pars plana vitrectomy with removal of posterior cortical vitreous,air-fluid exchange, instillation of autologous platelet concentrate onto the posterior pole and 20%~30%SF6 tamponade,were performed in treating 6 eyes of 6 patients with idiopathic macular holes. The patients were instructed to lie in a supine position for l hour after surgery,then adviced to remain in a facedown position for 2 weeks. Results Flattening of the surrounding retina and closure of the hole were achieved postoperatively in all the 6 affected eyes.Visual acuity improved two lines or more in 5 eyes (83.3%).Four eyes(66.7%)reached a postoperative visual acuity of 0.3 or more. Retinal detachment ocurred in one eye owing to peripheral new hole formation. Conclusion Pars plana vitrectomy, autologous platelet concentrate and gas tamponade for the treatment of full-thickness idiopathic macular holes are able to close macular hole and improve the visual acuity.
